Cadence: 2147483648 or 0 in a training session

hi there.
I was riding in a group training session, where the first section was “warm up” at some cadence. But most of riders in the event saw 0 or 2147483648 in the display (screenshot available).

It’s quite suspicious and of course unmanageable to spin faster even if you try :wink:

Hint: note that 2147483648 is a max value for signed 32 bit integer… overflow?
